The Scala 3 compiler, also known as Dotty.
## Compiler version 3.2.0 ## Minimized code ```Scala //file a.scala object betaReduceTest { inline def macroPolyFun[A](inline arg: A, inline f: [Z] => Z => String): String = ${ macroPolyFunImpl[A]('arg, 'f)...
Fixes https://github.com/lampepfl/dotty/issues/15562 Copy of https://github.com/lampepfl/dotty/pull/19756, and #19775 with a final tweak commit at the end. I created a new PR since the original PRs were not on staging.
Various proposed improvements to how Scala handles generic programming and type classes. They are summarized in this doc page: https://github.com/dotty-staging/dotty/blob/typeclass-experiments/docs/_docs/reference/experimental/typeclasses.md This PR is based on #18958.
When an experimental definition is used, the error message shows how to enable the experimental mode. Previously we only did this for experimental language features, but not for experimental definitions.
Make it easier to use experimental language features out of the box. We already have `-experimental` that enables experimental mode globally by adding the `@experimental` annotation to all top-level definitions....
This is to prepare the it for release. The name of the jar will be `scala2-library-tasty-experimental` to make it clear that it is not stable yet.
## Compiler version 3.0.0-3.4.1-RC1 ## Minimized example ```Scala trait Base { def func(): Unit } class Derived extends Base { def func(): Unit } ``` ## Output Error/Warning message ```...
